To CLZZ whmn it may concern:

Be it known that I, CHARLES A. BOYD, .a citizen of the United States of America, and

, aresident of Cleveland, county of Cuyahoga,

- avoiding much forging and reducing the expense and labor in the construction and repairs to a minimum. 7

The invention therefore consists in the new. constructions and combinations substantially as hereinafter described, and pointed out in the claims; 7

In the accompanying drawings, Figure l is a top or plan of the new truck. Fig. 2 is a side elevation of the new truck. Fig, 3 is an end elevation and half cross-section of the new truck. Fig. at is a vertical section of a part of the truck,showing the construction of the transom. Figs. 5, 6, 7, 8, and!) represent the details ofa casting used in the coustructionat the ends of the transom. Figs. 10, 11, 12, 13, andl-i represent the details of the'pedestals and journal boxes, showing their peculiar construction and arrangement. A is the frame of the truck and is composed of but two angle-bars bent at right angles at act to form the corners. Said bars are joined together at the middle of the ends of the ,frame at a b means of a iece of an le-bar Y P a A, riveted to the abutting ends of the bars A,

thusforming a very strong frame having very rigid corners.

The transom consists of two cross-bars of angle-steel B B, joined to the said bars A A at the middle part of the frame by means of triangular brace-plates B B, riveted onto both the bars A and B,'forming a stifi and strong joint. B" B are wide'cross-plates riveted to the cross-bars B B and depending therefrom. C O are cast-metal brackets secured to the said cross bars B B and plates 13" B" by means of rivets 0 c. v

DD are strong links suspended from the brackets O G by large bolts (1 d. The lower ends of sai'd'links are connected to blocks E E by large bolts 6 e, passing through said links and blocks.

' The brackets CC have. vertical tubular side projections C. Y The upperends'of said tu-- bular projectionsabut against the under side of the top frame-bars A, and their lower ends rest upon the arch brace-bars K K. Large bolts K pass through the plates B, the framebars A, the tubular projections 0 and the arch-bars K, thus making a strong support for the springs GG and bolster.

F is a channel-bar extending across the frame A, having its ends resting'on and supported by the blocks E E, and forms the lower cross-bar of the-transom.

G Gare elliptic springs supported in the seats 9 g on the transom cross-bar F.

H is a top or bolster cross-bar having its ends resting upon and secured to the spring cap-blocks h; h on the said springs G G.

I I are the rub-blocks, secured on the ends of the bolster-bar H and cap-blocks h h by the bolts ff.

J is the center turning-plate on the bolster H.

.The bolster-bar H is strengthened by the truss-bar H, secured at its ends between the ends of the bolster-bar and the spring capblocks 71. h by the bolts f f. The bolts jj, which secure the center plate J to the bar H, pass through sleeves jj', put between the bolster-bar H and the truss-bar H. p

L L are the pedestals, provided on one side with heavy projections L ,L, which form the upper bearings for the coil-springs S S. The pedestals are secured to the top frame A by the large bolts Z Z Z. The ends of the archbars K K arealso secured between the top of the pedestals and the frame A by the same bolts, as seen in Fig. 11.

. M M are the axle journal-boxes, on the un- ICO O O are the lower spring-seats, secured to the said equalizing-bars'N N by the bolts 0'. T T are tie=bars reaching from one'end of the truck to the other and extending under ported on the blocks E E, the springs G G the pedestals and secured thereto by bolts ti through the lugs "u 1 on the lower ends of the pedestals.

Having described my invention, what I claim is 1. The improved car-truck consisting of the angle-bar frame. A, the angle-piece crossbars B B and plates B B" secured to said cross-bars B B, the gusset-plates B B secured to the f ram e-bars A A and cross-bars B B, the brackets O 63 secured to the cross-bars B B and gusset-plates B B and plates B" B" the arch brace-bars K K extending between the pedestals; the tubular projections O on the brackets G 0, bolts K through the plates B, frame A, tubular projections and the archbars K, binding them together, the blocks E E supported on the arch-bars K K, the links D D suspended from the brackets C O by the bolts 01 d, and connected to the blocks E E by the bolts e e, and the lower cross-bar'F supsupported on the cross-bar F, and the bolster H supported on the springs G G, constructed and combined substantially as described.

2. In car-trucks, the combination with the pedestalsL L, having the spring-bearing projections L L, the axle-boxes M M, having lugs m 'm, the equalizing-bars'N N secured in said lugs, spring-seats O 0 supported on the equalizing-bars, and the coil-springs S S, supported in said seats and supporting the pedestals; of the frame A composed of the two angle-bars A A, joined at the middle of the ends of the frame, and comprising the sill, side and ends of the truck-frame, as shown and described.

Signed by me, at Cleveland, Ohio, this 31st day of May, 1898.
